Treatment Option Overview



There are different types of treatment for patients with childhood rhabdomyosarcoma.

Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment.

Because cancer in children is rare, taking part in a clinical trial should be considered. Some clinical trials are open only to patients who have not started treatment.

Children with rhabdomyosarcoma should have their treatment planned by a team of health care providers who are experts in treating cancer in children.

Because rhabdomyosarcoma can form in many different parts of the body, many different kinds of treatments are used. Treatment will be overseen by a pediatric oncologist, a doctor who specializes in treating children with cancer. The pediatric oncologist works with other health care providers who are experts in treating children with rhabdomyosarcoma and who specialize in certain areas of medicine. These may include the following specialists:

Some cancer treatments cause side effects months or years after treatment has ended.

Side effects from cancer treatment that begin during or after treatment and continue for months or years are called late effects. Late effects of cancer treatment for rhabdomyosarcoma may include:

  • Physical problems.
  • Changes in mood, feelings, thinking, learning, or memory.
  • Second cancers (new types of cancer).

Some late effects may be treated or controlled. It is important to talk with your child's doctors about the effects cancer treatment can have on your child. (See the PDQ summary on Late Effects of Treatment for Childhood Cancer for more information.)

Three types of standard treatment are used:

Surgery

Surgery (removing the cancer in an operation) is used to treat childhood rhabdomyosarcoma. A type of surgery called wide local excision is often done. A wide local excision is the removal of tumor and some of the tissue around it, including the lymph nodes. A second surgery may be needed to remove all the cancer. Whether surgery is done and the type of surgery done depends on the following:

  • Where in the body the tumor started.
  • The effect the surgery will have on the way the child will look.
  • The effect the surgery will have on the child's important body functions.
  • How the tumor responded to chemotherapy or radiation therapy that may have been given first.

In most children with rhabdomyosarcoma, it is not possible to remove all of the tumor by surgery.

Rhabdomyosarcoma can form in many different places in the body and the surgery will be different for each site. Surgery to treat rhabdomyosarcoma of the eye or genital areas is usually a biopsy. Chemotherapy, and sometimes radiation therapy, may be given before surgery to shrink large tumors.

Even if the doctor removes all the cancer that can be seen at the time of the surgery, patients will be given chemotherapy after surgery to kill any cancer cells that are left. Radiation therapy may also be given. Treatment given after the surgery to lower the risk that the cancer will come back, is called adjuvant therapy.

Radiation therapy

Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or stop them from growing. There are two types of radiation therapy.

External radiation therapy uses a machine outside the body to send radiation toward the cancer. Certain ways of giving radiation therapy can help keep radiation from damaging healthy tissue. These types of external radiation therapy include the following:

  • Conformal radiation uses a computer to create a 3-dimensional (3-D) picture of the tumor. The radiation beams are shaped to fit the tumor.
  • Intensity-modulated radiation therapy (IMRT) uses images created by a computer that show the size and shape of the tumor. Thin beams of radiation of different strengths are aimed at the tumor from many angles.
  • Fractionated stereotactic radiation therapy uses a rigid head frame attached to the skull to aim radiation directly to a tumor. This causes less damage to nearby healthy tissue. The total dose of radiation is divided into several small doses given over several days. This type of radiation therapy may be used for rhabdomyosarcoma of the head and neck. This procedure is also called stereotactic external-beam radiation therapy and stereotaxic radiation therapy.
  • Proton-beam therapy is a type of high-energy, external radiation therapy that uses streams of protons (small, positively-charged particles of matter) to kill tumor cells.

Internal radiation therapy (brachytherapy) uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. Internal radiation therapy is used to treat cancer in areas such as the vagina, vulva, bladder, prostate, head, or neck.

The type and amount of radiation therapy and when it is given depends on the age of the child, the type of rhabdomyosarcoma, where in the body the tumor started, how much tumor remained after surgery, and whether there is tumor in the nearby lymph nodes.

Chemotherapy

Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). Combination chemotherapy is treatment using more than one anticancer drug. The way the chemotherapy is given depends on the type and stage of the cancer being treated.

Every child treated for rhabdomyosarcoma should receive chemotherapy to decrease the chance the cancer will recur. The type of anticancer drug, dose, and the number of treatments given depends on whether the child has low-risk, intermediate-risk, or high-risk rhabdomyosarcoma.

See Drugs Approved for Rhabdomyosarcoma for more information.

New types of treatment are being tested in clinical trials.

This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site.

High-dose chemotherapy with stem cell transplant

High-dose chemotherapy with stem cell transplant is a way of giving high doses of chemotherapy and replacing blood -forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells.

Immunotherapy

Immunotherapy is a treatment that uses the patient’s immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body’s natural defenses against cancer. This type of cancer treatment is also called biologic therapy or biotherapy.

Targeted therapy

Targeted therapy is a treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Targeted therapy with angiogenesis inhibitors is being studied to treat childhood rhabdomyosarcoma. Angiogenesis inhibitors keep blood vessels from forming in a tumor. This causes the tumor to starve and stop growing or to shrink. Monoclonal antibodies and kinase inhibitors are two types of antiangiogenic agents used in clinical trials for childhood rhabdomyosarcoma.

Monoclonal antibody therapy uses antibodies made in the laboratory, from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Monoclonal antibodies used in clinical trials for childhood rhabdomyosarcoma attach to and block substances that cause new blood vessels to form in tumors. Monoclonal antibodies may be used with chemotherapy as adjuvant therapy.

Kinase inhibitors stop cells from dividing and may prevent the growth of new blood vessels that tumors need to grow.

Patients may want to think about taking part in a clinical trial.

For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.

Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.

Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.

Patients can enter clinical trials before, during, or after starting their cancer treatment.

Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.

Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.

Follow-up tests may be needed.

Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. This is sometimes called re-staging.

Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your child's condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
